Tabbed Content

VI-B is specifically formulated to slow estrogen production with precision.  Testosterone impacts more than your muscles and sex drive; it motivates you towards your goals. 

The problem is when testosterone is elevated, so is its little sister, estrogen. That's when VI-B comes in.  Estrogen production is the product of the aromatase enzyme, which converts testosterone into Estrogen.  Testosterone is thought of as the king of the hormones, but managing estrogen is just as important.   The benefits of reduced estrogen include increased strength, enhanced muscle growth, reduced recovery time, a harder physique and an increased libido.

Estrogen control also helps minimize the onset of gynecomastia, helps control “mood swings” and helps yield “dry” gains.  VI-B is composed of 4'-methoxy-5,7-dihydroxyflavone (Acacetin), a naturally occurring O-methylated flavone that has been clinically shown to significantly suppress aromatase activity in the body, promoting maximum testosterone levels.

Even though testosterone is thought of as the male hormone, these results are for everyone. There are no gender requirements for hormonal optimization. By decreasing estrogen production, you will be able to get leaner, harder and drier than ever before.  If you're looking for the best version of you, look no further than VI-B.

VI-B helps:

  • Decrease recovery time
  • Attain harder physique
  • Increase libido
  • Control mood swings
  • Control estrogen aromatase
  • Support healthy testosterone levels
  • Increase muscle mass
